Largest solar system ever known: Planet orbits star 1trn km away

A new study discovered that a planet previously thought to be a loner actually orbits a star 1 trillion kilometers away from it. It takes it a million Earth years to orbit its sun, making it the largest solar system found to date.

The giant gas planet – identified only as 2MASS J2126−8140 by scientists – lies 100 light years away from Earth. It’s around 12 to 15 times the mass of Jupiter, the largest planet in our Solar System.
